Shell construction uses a thermo-injected shell with a special polymer blend and variable thickness, delivering an optimal combination of impact protection and lightweight comfort.
A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration forces from oblique impacts, acting as a slip plane that mimics the brain's cerebrospinal fluid.
The patented visor release system ensures the visor detaches at a controlled, pre-determined force to help reduce neck loads during an impact.
Ventilation is maximized with ten inlets and seven exhaust ports for efficient heat transfer and airflow management.
